York S1-031-01954-000 Defrost Time & Temperature Control Board

The York S1-031-01954-000 Defrost Time & Temperature Control Board is an essential component that manage defrost operation within heat pumps and air conditioning units in the HVAC system. This control board track both temperature readings and time limits to achieve effective defrosting operation, which stop outdoor coil ice formation and support system performance. This control board optimize energy efficiency because it start defrost cycles only when essential, reducing pressure on the compressor and extending the overall system lifetime. This control board bring reliable precision to operate effectively through heating and cooling control with steady airflow.
